Beeley, Eugene Oreg., assignor, by mesne assignments, toKlamath-Ward, Inc., Eugene, 0reg., a corporation of Oregon Filed Mar. 2,1964, Ser. No. 348,661 8 Claims. (Cl. 14337) This invention relates toan edger for sawing cants in-to boards, and more particularly to acantilever type edger.

An object of the invention is to provide a new and improved edger.

Another object of the invention is to provide an edger of the cantilevertype.

A further object of the invention is to provide an edger of the utmostsimplicity in construction and occupying a minimum space, while havingmaximum precision.

Another object of the invention is to provide an edger having anelectric motor drive in which a saw arbor is mounted in cantilever styleon the edger and the motor is connected between two side frame plates toprovide the frame for the saws.

The invention provides an edger having a frame comprising a pair of sideplates and an electric motor positioned between the side plates andconnected to the side plates to form a rigid frame therewith with a sawarbor connected to one end of the motor and supported in cantileverfashion thereby. Preferably infeed and outfeed rolls are hung by acantilever framework from one of the side plates along with pressermeans for holding cants and boards against the infeed and outfeed rolls,respectively.

In an edger forming a specific embodiment of the invention there isprovided a pair of vertical side frame plates between which there ispositioned a double ended motor which is connected to the two sideplates and forms' a rigid frame therewith. Saw arbors are mounted on theends of the motor shaft and extend outwardly from each end of the motor.Infeed rolls and outfeed rolls are mounted on opposite sides of the sawarbors and are supported by tubular frameworks carried by the sideplates and pressers for the infeed and outfeed rolls are carried by theside plate and comprise pivotal frames carrying aplurality of pneumatictires rotatably in side-by-side relationship for pressing downwardlyagainst the cants and boards. If desired, the arbors on one or bothsides of the motor may be provided with shiftable saws thereon, and sawguides engage the saws and are connected to setworks mounted between thetwo side plates, and an electric motor for driving the presser rollsalso is mounted in the space between the two side plates so thatcompactness is provided.

A complete understanding of the invention may be obtained from thefollowing detailed description of an edger forming a specific embodimentthereof, when read in conjunction with th appended drawings, in which:

FIG. 1 is a fragmentary, top plan view of an edger forming oneembodiment of the invention;

FIG. 2 is a partially sectional view taken substantially along line 22of FIG. 1; and

FIG. 3 is a vertical, sectional view taken along line 3-3 of FIG. 1.

Referring now in detail to the drawings, there is shown therein an edgerto which is fed slabs and cants by an infeed 12 and which saws the slabsand cants into boards into a rigid frame work by plates 24 and 26 andhousings Patented Sept. 27, 1966 28 and 30 of motors 32 and 34respectively. The motors are fastened rigidly to the plates and 22 bycapscrews 36 connecting flanged or belled ends 38 of the motor housingsto the plates. The motors 32 and 34 are commercially availableelectn'cmotors, and are of the double ended type having heavy dutybearings at each end of each of the motors, and have double ended shafts40 rigidly carrying the rotors of the motors. At the righthand ends ofthe motors 32 and 34, as viewed in FIG. 1, there are mounted saws 42,44, 46 arid 48 in laterally fixed positions on saw arbors 50 and 52, andat the lefthand side of the edger 10, as viewed in FIG. 1, there areprovided saws 54, 56, 58 and 60 mounted in laterally adjustablepositions on saw arbors 62 and 64, the saws 56 and 60 being adjustablelaterally relative to one another by groups of setworks 66 and 68mounted as two units by brackets illustrated by bracket 70, whichcarries the setworks 68 adjustably thereon by means of screw 72 and nut74 clamping the screw 72 adjustably to the bracket 70, the screw 72being rigid with one of the setworks 68, each of the setworks 68 beingprovided with such mounting elements. Thus the setworks 66 and 68 aremounted between the plates 20 and 22 so that no extra overall space isrequired for the setworks.

The arbor 50 has a tapered socket (FIG. 3) therein fitting closely upontapered end 82 of the shaft 40 and locked tightly on the tapered end 82,which is complementary to the socket 80, by an elongated capscrew 84threaded into tapped bore 86 in the tapered end 82. The screw 84 locksthe arbor 50 to the shaft 40 rigidly and in alignment with the shaft 40.The arbor 50 has a cup-shaped flange 88 at the inner end thereof, andthe flange 88 cooper-ates with a torque plate 92 splined to the arbor 50and pinned to the saw 42 to key the saw 42 to the arbor 50. The saws 44are mounted by torque plates 92 and a retaining nut 94 on the arbor andare splined thereto to key the saws 44 to the arbor 50-. The arbor 50and the saws 42 and 44 thereon may be removed from the shaft 40 as aunit merely by unscrewing the elongated capscrew 84 and pulling thearbor 50 off the tapered end 82 of the shaft 40, and another unitidentical therewith may be placed on the shaft 40 while the saws of theremoved unit may be sharpened or otherwise treated for maintenance. Thearbors 52, 62 and 64 are mounted on the shafts 40 of the motors 32 and34 by identical structure, which will not be described in detail.

As illustrated in FIG. 3, both flanged ends 38of the housing 28 of themotor 32 have reduced end portions or bosses whose external surfaces areprecisely concentric with the shaft end 40 and which fit into preciselyformed, aligned bores 102 formed in the side plates 20 and 22. The endsof the motor housing 60 are similarly positioned in aligned bores in theplates 20 and 22. The upper saws 42, 44, 54 and 56 are mounted inhorizontally offset and vertically overlapping positions relative to thelower saws 44, 4'8, 58 and 60, respectively, as illustrated best in FIG.2, with each of the opposed pairs of upper and lower saws cuttingslightly over halfway through a cant or slab of nominal thickness. Thesaws 42, 46, 54 and 58 saw outer cuts in the cants and slabs, and travelthrough wane, knots and rough material more than the saws 44, 58, 56 and'60, and consequently are made substantially thicker and more ruggedthan the saws 44, 4s, 56 and 60. That is, the saws 42, 46, 54 and 5s aresubstantially more rugged for the more rugged duty required therefrom.

' is supported by a tubular support 118 fixed rigidly at one To feedcants to the saws 42 and '48 there is provided an edger infeed (FIGS. 1and 2) including driven roller infeed rolls 112 and 114 journaled inbearings carried by the plate 22 and by a plate 1'16. The plate 116 endto the plate 22 and to the other end of which the plate 116 is rigidlysecured. The edger infeed 110 includes a presser 120 for holding thecant tightly against the rolls 11-2 and 114. The presser1 20 includes ashaft 122 journaled in the plates 22 and 116 having arms 124 and 126keyed rigidly thereto, the arms mounting at the outer ends thereof anaxle 128 secured thereto by setscrews 130. The axle 128 carries atspaced points therealong pneumatic tire wheels #136 having tires 137preferably provided with annular grooves 138, the wheels 136 havingbearings 140 mounted on the axle 128, the bearings 140 being suitablyfixed against longitudinal movement along the axle 128 to maintain thespacing of the wheels 136 on the axle 128. A torsion spring 142 fixed atone end to a pin 144 rigidly carried by the plate 22 has its other endconnected to a pin 146 fixed rigidly to the arm 126. 'The spring 142biases the arms 124 and 126 clockwise, as viewed in FIG. 2, to press thepneumatic rubber tires of the wheels 136 downwardly against the cant topress the cant against the rolls 1-12 and 114, which have roughened ortoothed surfaces to drivingly engage the lower face of the cant andadvance the cantto the saws above the arbor 52 and below the arbor 50.

As best illustrated in FIGS. 1 and 2, the rolls 112 and 114 are drivenin clockwise directions, as viewed in FIG. 2, by an electric motor 150mounted below the motors 32 and 3-4, a chain 152, a sprocket 154 keyedto shaft 156 journaled in the plates -20 and 22, chain 157 driven by asprocket 158 mounted on jack shaft 160, sprocket 1'62 keyed to the jackshaft 160, a second sprocket .164 keyed to the jack shaft 160, which isjournaled in the plate 22, a chain 166 and a sprocket 168. The boardsand wane sawed from the cant are fed from the saws 42, 44, 46 and 48 byan edger outfeed 170 which is identical with the infeed 110 but ishanded relative to the infeed 110 but driven in the same direction. Theoutfeed 170 is also driven by the motor 150 through a chain and sprocketdrive 172 substantially identical, but reversed relative to, the chainand sprocket drive of the infeed rolls 112 and 114. At the lefthand sideof the edger 10, as viewed in FIG. 1, there is provided an edgerinfeed-180 of similar construction to the edger infeed 110 and alsothere is provided an edger outfeed 182 similar to the outfeed 170.

The mounting of the pneumatic tire wheels 136 of the edger infeeds '110and 180 and outfeeds 170 and 182 is identical, and is best illustratedby the wheel '136 of the outfeed 182 shown in cross-section and whichincludes a pneumatic tire 137 carried by a rim 174-mounted by hearing175 and having an inner race 176 spaced by sleeves 177 and 178 on axle128. The bearing 175 provides a low friction mounting for the wheel 136,and the parallel, circumferential grooves 138 provide excellent guidesto grippingly engage the cants and slabs and the boards and wanes sawedtherefrom to cause them to advance at rig-ht angles to the arbors 50,'2, 62 and 64.

By precisely mounting the precisely formed end portions 100 of thebelled ends 38 of the motors 32 and 34 in the precisely milled bores 102in the plates and 22, the arbors 50, 52, 62 and 64 are kept in preciselyparallel positions, the arbors 50 and 62, of course, being exactlyaligned and the arbors '52 and "64 also being exactly aligned with eachother. The saws 42, 46, 54 and 58 are mounted on the arbors62 and 64 infixed positions thereon, as is well known in the edger art, while thesaws '56 and 60 are mounted by saw mounting bushings 190 and 192 whichare splined to the arbors 62 and 64, and the bushings 190 and 192 havegrooves 194 and 196 therein into which plates 198 and 200 of thesetworks 66 and 68, respectively, project to slide the bushings 190 and192 and the saws 56 and 60 carried thereby along the arbors 62 and 64 todesired positions.

The above described edger 10 is a very precise machine, is constructedwith a maximum simplicity and a minimum number of parts and is veryrugged in its construction. Other arrangements utilizing the principlesof the invention may, of course, be made. For example, only one arborand the sawsmounted thereon may be utilized to .saw cants and wanesrather than to have two arbors mounting opposed saws thereon. Also, itmay be desirable to have an arbor at only one end of the motor.

It is to be understood that the above-described arrangements are simplyillustrative of the application of the principles of the invention.Numerous other arrangements may be readily devised by those skilled inthe art which Willembody the principles of the invention and fall withinthe spirit and scope thereof.
